I would balance the fridge cabinet wall by having the fridge centred between two narrower pantry cabinets as it currently feels far to heavy for your space. Alternatively, I would recommend having a narrow pantry on the left of the fridge with a full height cabinet with counter on the right with an upper cabinet above. This would help your space feel larger.

Any pictures of kitchen, design?

I think the only way you can do that is to swop the positions of the oven/range and the storage drawers. I'm sure it's doable, but there might be practical problems.

Your layout for you kitchen looks really good and would fit well with the mixture of black and white cabinetry. With the lament bench top, we would suggest melamine (entry level cabinetry) or acrylic bench top, which can come in high gloss feature or matt. The matt surface would go lovely with your choice of bench top, and acrylic is also a affordable cabinetry material. Below are some examples of how Reno4u has incorporated both black and white cabinetry together, without making it to dominantly dark. We feel as if these examples would be perfect for your layout, and depending on if you want more black cabinetry or white you can go either way. This design above is an example with more black than white, can be made matt or gloss with different handles/splash back and wallpaper. With a u shaped kitchen similar to yours, however from the pictures you provided your style may include different design below the island bench. Another kitchen designed by us which shows more white than black, with a bar built in which may suit your design better. We hope this helps you, please feel free to call us on 03 423 9067 and we can provide a free quote for materials and kitchen design, and help you finalise your design further. :)
